Title: Lubricating system
IPC: F16N25/02
Filed: 1964-04-15
Abstract: 1,026,840. Lubricating systems. EATON MANUFACTURING CO. April 15, 1964 [April 17, 1963], No. 15653/64. Heading F2A. In a lubricating system lubricant is fed to a bearing 6 by a pump through a metering valve 2, 3 or 4 (Fig. 1, not shown) and a flow-sensing device 7 comprising blocks 10 ... 14 containing pistons 26, 27, 28 lodged in bores 23, 24, 25 which are connected to said valve by a pipe 5, indicating means, e.g. a signal lamp 8, being actuated by the device when it completes a cycle of operations to indicate proper flow of lubricant to the bearing. Said blocks are separated from one another by gaskets 15 ... 18 to provide lubricant passages therebetween, each gasket having peripheral portions 19, 20 and a central portion 21. Each of the pistons has four lands 29 ... 32, the intermediate lands being situated on either side of a port 41, 42 or 43 connected to said pipe by a passage 40. When piston 26 is in the position shown, lubricant enters a space or chamber 47 in bore 24 through port 41, bore 23 and passages 44, 45, 46, thereby causing piston 27 to move to the right and displace a quantity of lubricant in a chamber 51 through passages 52, 53, 54, bore 23 and passages 55, 56 to the bearing. Subsequently, lubricant enters a chamber 58 in bore 25 through port 42, bore 24 and passages 61, 62, 63, thereby causing piston 28 to move to the left and displace a quantity of lubricant in a chamber 67 through passages 68, 69, 70, bore 24 and passages 71, 72, 56 to the bearing. Thereafter, lubricant enters a chamber 34 in bore 23 through port 43, bore 25 and passages 75, 76, 77, thereby causing piston 25 to move to the right and displace a quantity of lubricant in a chamber 35 through passages 78, 79, 80, bore 25 and passages 82, 56 to the bearing. Three further quantities of lubricant are fed to the bearing in a similar manner, the final quantity in the cycle being delivered by piston 26 returning to the piston shown. Movement of piston 26 from right to left effects actuation of a sensing mechanism, e.g. a limit switch (not shown), by a rod or stem 88 attached to the piston. An alternative embodiment of the sensing unit (Figs. 3 to 6, not shown) mainly differs from that shown in that it comprises pistons 104, 105, 106 lodged in bores 101, 102, 103 formed in a single block 90 carrying a limit switch 94 which is actuated by a stem 99 on piston 105 at the end of each cycle of operations. When lamp 8 is energized at the end of each cycle, a timer T (Fig. 1) is re-set and started, whereby failure of the sensing device to complete the next cycle in a pre-determined time interval allows the timer to close a switch S to effect operation of a further signal lamp 9. Lamps 8, 9 may be replaced by audible signalling means.

Abstract: 1,205,033. Open end spinning. MASCHINENFABRIK RIETER A.G. 18 Aug., 1967 [24 Aug., 1966], No. 15656/70. Divided out of 1,205,031. Heading DID. In an open end spinning device, wherein a yarn reserve is created between the spinning chamber and the take-up means 27 to be fed back after a yarn break or on stoppage of the machine, the yarn reserve is held in its extended path by a support 24 which can be removed from the yarn while the yarn is in its fully extended path. As shown the support is a solenoid retractable pin 24 which releases the yarn when a drop in tension is sensed by a member 25. The reserve is re-created by a solenoid operated lever 33.

Abstract: 386,526. Cooking-ovens. LEWIN, J. 53, N³rnbergerstrasse, Berlin. June 2, 1932, No. 15671. [Class 126.] In cooking-apparatus for use on gas stoves, burners, &c., and of the kind comprising a base carrying an open-ended cylindrical casing and a covering hood, the base comprises two or more concentric, spaced, and interconnected rings 3, 4 which serve as a support for a utensil and have notches 5 in their upper edges through which the gases pass. In the constructions shown, the outer ring 3 is provided with an inclined flange 7 which supports the cylindrical casing 8<1>, and is formed with a groove 7a and screw plug 7b for collecting and disposing of condensates. Both the casing 8<1> and hood 91 may be double-walled, as shown, to form heat-insulating jackets, the top of the hood being formed as a double jacket. Apertures 14 for the discharge of gases are controlled by dampers 13 carried by arms on a central rotatable spindle, the construction shown in Fig. 5 employing one set of dampers, and that shown in Fig. 9 three superposed sets. Further escape apertures 17, Fig. 5, may be found in the lower edge of the hood, and be controlled by a movable annular plate on the hit-and-miss principle. Similarly controlled air inlet apertures may be provided in the flange 7. Shelves 21, Fig. 9, may be supported by means of laterally-extending lugs resting on flanges 22, the flanges being gapped for the passage of the lugs to allow the shelves to be transferred from one position to another. The apparatus may be of cylindrical or other form, and may be constructed to cover more than one burner. The casing may be provided with doors, and may be made integral with the flange 7. The hood and casing may be made of heat-proof glass, or as water-heating receptacles.

Abstract: 199,746. Joannides, C. June 29, 1921. Dental flasks.-In the manufacture of dental rubber plates by the injection process described in Specification 165,879, the filling of the mould is controlled without opening the boiler. The moulding flask A with movable bottom B and cover C has a conical inlet opening I to receive an injector nozzle N. The injector cylinder M is screwed through an opening formed in the boiler D, and is fitted with a screw plunger T and hand-wheel Y. The outlet opening J receives a tubular screw plug d, which passes through a projection e of the boiler and screws the flask in position. In operation, the cylinder M is retracted in order to allow steam to pass through the flask and scour out the wax, whereupon the cylinder is advanced to bring the nozzle into contact with the inlet seating. Rubber is then injected, and the filling of the mould is indicated by escape of material through the plug d. The injector piston may then be retracted and a pin inserted in the plug to force back excess rubber. During vulcanizing the plug d is replaced by a solid closing plug.
